Application filed January 2, 1917. Serial N 0. 140,136.

To all whom it may concern:

Be it known that I,FRA1\K D. MALTBY, a citizen of the United States, residing at Battle Creek, county of Calhoun, State of Michigan, have invented certain new and useful Improvements in Priming and Decarbonizing Devices for Internal-Comhustion Engines, of which the following is a specification.

This invention relates to improvements in priming and decarbonizing devices for in ternal combustion engines.

The main objects of this invention are:

First, to provide an improved priming and decarbonizi'ng device for internal combustion engines which may be quickly and easily operated to prime the engine or to ad just the device to conduct water to the en'- gine for decarbonizing purposes.

Second, to provide an improved device of the class described which mayhe, applied to motor vehicle engines, so as to be operated from the dash or from the front of the vehicle. 7

Third, to provide an improved device of the class described Which does not interfere with the normal operation of the carburetor,

but which, if desired, may be adjusted to supplement the carbureter inits normal op oration. 0

Fourth, to provide an improved device having these'advantages which is comparatively simple in its parts and not likely to get out of repair or to become inoperative. Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:

Figure I is a detail side elevation of an adaptation of a structure embodying the features of myinvention, it being shown in operative relation to a carbureter, manifold,

and radiator.

Fig. II is an enlarged detailview, partially in longitudinal section, on a-line corresponding to line 22 of Figs. I and III.

III is an enlarged detail section'on a line corresponding to line 33 of Figs. I, II and V. r

Fig. IV is an enlarged detail section through the air and water valve showing structural details thereof.

Fig. V is a detail section on a line corresponding to line 55 of Figs. II and III, showing further details of the air and water valve and its connection to the manifold.

Iiig. VI is a detail section on a line cor responding to line 66 of Figs. I, V and VII, showing the arrangement of the return spring for the air and water valve.

Fig. VII is an enlarged detail of the co1n bined air and water valve.

Fig. VIII is an elevation view of the air and water valve hand piece and indicator.

Fig. IX is-.a detail section on a line corresponding to line 9-9 of Fig. I, showing details of the means for operating the plunger when it is used as a regulating valve.

Fig. X is a detail side elevation of an adaptation of my improvements with the primer actuating rod arranged through the radiator ofa motor vehicle.

In the drawing similar reference char actors refer to similar parts throughout the several views, and the'sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, 1 designates the manifold of an internal combustion engine, and 2 the carbureter. The manifold illustrated is that of the Ford automobile. 3 represents the radiator, and a the dash or front of the vehicle.

I provide'a priming pump cylinder 5 and a coacting plunger 6. the plunger being provided with a. suitable packing 7 and a rod '8 which projects from the cap 9 of the cylinder to be operated at the instrument board or dash, as shown in the adaptation of Fig. I, or at the front of the machine, as shown in Fig. X, in which the rod 8 is arranged through the radiator in convenient position so that the primer may be actuated and the engine cranked in quick succession.

The adaptation shown in Fig. I is desirable where the vehicle is provided with a and spraying nozzle 12 which projects cen- I trally' into the manifold cylinder. The

livery; passage is provided with a return check 13' held. upon its seat by thespring Ll, the otter end of the spring being seated against the nozzle. The plunger is held normally in its initial position by means of the coiled spring 15 which is arranged on .Kger rod 8, as shown in Fig. .il'. The inner end of the plunger is beveled at 16 so that it may be adjusted to constitute a regulating valve for the delivery port 17.

The inlet valve 18 of the cylinder is seated in the tubular valve seat member 19, which is arranged in the inner end of the cylinder and shohldered at 20, see Fig. III. This valve seat member is clamped in place by the coupling 21. The fuel supply pipe 22 leads from this coupling 21 to the fuel supply 23 of the carbureter, see Fig. I. The valve 18 is held on its seat by the plunger when the plunger is in its initial position. A coiled spring 24 on the stem 25 of the inlet valve tends to close this valve. These parts are the same, or substantially the same, as those illustrated and described in my companion application, Serial Number 139,837, filed Dec, 1916, in which I make claims thereto.

The passage arm 11 contains a second passage 26 delivering into the manifold and terminating without the manifold. in an annular groove 27 about the arm.

I provide an air andwater inlet valve comprising a casing 28 having a sleeve or bracket 29 mounted upon the passage arm to embrace the groove 27. This sleeve is rotatable upon the arm to permit the adjustment of the valve either to the position shown in the adaptation of Fig. 1' or that of X, or other desired positions.

The valve casing 28 is provided with a delivery port 30 registering with the groove 27 and with an air inlet port 31 and a water inlet port 32. The water inlet port is connected by the conduit 33 with. the radiator 3 or other source of water supply so as to receive water therefrom.

The valve 3% is provided with a port adapted to connect either ports 31 or 32 with the delivery port 30, so that either air or water may be delivered to the manifold or When the valve is closed both ports are cut ofl'. I

The valve 34 is of the rotary tapered plug type and is held in its seat by the spring 36. The stem 37 of this valve is arranged through thedash and provided with a finger piece 38 and an index 39, an index plate 40 being mounted in coacting relation to this index finger and provided with suitable indicia indicating the air and water delivering positions of the valve.

As the embodiment illustrated is only designed to deliver water when it is desired to decarbonize the eylindersthe valve stem which are in use,

nee s-e3 is provided with a spring all mounted on the valve stem 37 and connected thereto at one end by means of the collar 42 and set screw The inner end. of the spring terminates in an arm lat adapted to engage with the shoulder or stop 45 on the valve casing wheu the valve is turned to connect the Water port 32 1- ho spring being thereby put under tension so that as soon as the stem is released the valve is actuated to cut off the water.

The applicant has found that by occasion-- ally supplying water for shortperiods the cylinders may be very effectively decarbonized.

It is desirable, under certain conditions, that an additional or supplemental supply of air be delivered to the manifold.

By adjusting the valve 34 to connect the air inlet port; 31 a. supplemental supply of air is delivered to the manifold. The spring is inoperative when the valve is adjusted to this position So that it remains in its adjusted position until manually shifted.

The plunger provided with a suitable fingerpiece 46 which is, in the adaptation of Fig. I arranged through the dash in convenient position for manipulation. lVhen the plunger is used as a regulating valve for the discharge port 17 I operate the same by means of a lever l? which forked at 48 to engage the collar 49 on the plunger rod the lever being pivoted at 50 in convenient position to be operated by the foot of the driver. A. stop screw 51 is provided to limit the movement of the plunger.

In the event that the carbureter becomes inoperative or an. additional supply of fuel desired the plunger may be retracted and the fuel is then drawn through the primer into the manifold, and, owing to the position of the nozzle l2, it is effectively atomized by the incoming air,

My improved priming and decarbonizing device simple in structure and is easily in stalled or applied to engines as commonly (fOllSi'lllUl'Gtl and may be adapted for manipulution from the front of the vehicle as is desirable where the engine is to be cranked by hand or operated from the dash or instrument board where the vehicle is provided with a self-starter or cranking means.

The device is mounted so that the noyzlc is central in the manifold. thus providing :1 uniform distribution to the several cylinders.

I have illustrated and described my im provements in the form in which I have embodied the some in use. I have not attempted to illustrate or describe various modifications which might be my improvements to meet different conditions and the various forms of manifolds I believe the disclosure made will ena le those skilled in the art to desirable for adapting Cir which my invention relates to embody or 1:30

adapt the same as conditions may require. I desire, however, to be understood as claiming my invention in the form illustrated as well as broadly within the scope of the appended claims.
